y 5, 1931- H. SCHWARZE DISTRIBUTOR MOUNTiNG Filed Nov. '7, 1927 (MoanPatented May 5, 1931 Application filed November 7, 1927. Serial No.231,754.

This invention relates to a distributor mounting for an internalcombustion engine.

It is an object of this invention to provide a new and improveddistributor mounting which will provide for accurate manual sparkadjustment in addition to the full automatic adjustment provided in thedistributor.

It is a further object of the invention to provide a distributormounting of this character which will allow a slight amount of end playin the distributor shaft so that binding of the parts, and theconsequent friction and overheating, will be avoided.

It is a further object of the invention to arrange the distributor shaftin such a way that the oil pump normally carried at the lower end of thedistributor shaft may be placed outside of the crankcase and in anaccessible position.

Other objects and advantages of the invention will appear in the courseof the following description, taken in connection with the accompanyingdrawing and appended claims.

In the drawing: 7 V

Fig. 1 is an end view, with parts broken away and in section, of part ofa conventional-internal combustion engine in which is embodied myinvention.

Fig. 2 is a. view on the line 2-2 of Fig. 1.

Fig. 3 is a plan view of the fastening plate shown in the precedingfigures.

Fig. 4 is an exploded view,'showing apart of the engine, the clampingplate, and the pointer.

Referring to the drawing, I have illustrated in Fig. 1 an internal ginecomprising an engine block or casting and camshaft 12. The cam shaft 12is provided-with a worm gear 14 which meshes with pinion 16 fixed on thedistributor shaft by means of a pin 17 which extends through the shaft18 and through apertures 1n the sleeve portion of pinion l6. Shaft 18,as shown in the drawing, is set at an angle to the vertical and isjournalled at 1 its lower end in ably secured in outside of the abearing 19 which is suitthe engine block. On the engine block, on theside thereof opposite that on which the distributor is located, there isprovided an oil pump 23 into which open intake and discharge conduits24; The shaft 21, which carries the driving pinion 22 of the pump, isjournalled in the bearing 19 and the driving connection therebetween.

The upper portion of the distributor shaft is journaled in a housingwhich extends through an aperture in the engine block. Surrounding thehousing 20 just outside the engine block is a bifurcated plate or stamp-26 for rigidly fixi g the plate to housing 20. Plate 25 is fixed to theengine block b bolt 27. Set bolt 27 is plate 25 and housing 20 relativeto the engine block. A graduated scale 36 concentric with housing 20 isprovided on the lower portion of plate 25.

urrounding housing '20 just above the plate 25 is the pointer 32 whichis provided with a longitudinally extending slot 33 connecting with theopening which is adapted to receive the housing 20. Thepointer 32comprises a stamping which is roughly of an inverted cup shape, or, inother words, is flanged downward about its periphery. Extending throughthe side flanges in the region of the slot 33 is a clamping bolt 34 bymeans of which the pointer can be clamped to housing 20. At its upperend the housing 20 carries the usual distributor mechanism (not shown indetail).

e housing is set at the at the factory and no manual adjustment isordinarily required. If such adjustment becomes necessary, however, bolt26 may be loosened and the housing 20 and pointer 32 rotated the desiredamount either direction.

proper position v and contraction or from The bolt 26 is then tightenedto clamp the housing 20 firmly in position.

In assembling the parts at the factory, the distributor shaft 18carrying the usual parts of the distributor mechanism is inserted in thehousing 20 from the upper end and the pinion 16 then keyed thereto. Itmay be noted that the upper end of the pinion sleeve 15 fits snuglyagainst the lower end of housing 20, thus permitting rotation but notlongitudinal movement of the shaft and housing relative to each other.Plate 25 is then placed over the opening in the engine block and isfixed in position by means of bolt 27. Pointer 32 is then fixed in itsproper place on housing 20. Housing 20 is then inserted in the engineblock and the lower end of shaft 18 pushed down into the housing 19 ofthe oil pump shaft. \Vith the pointer. '82 abutting against plate 25,the bolt 26 is tightened, thus clamping plate 25 to housing 20. Sincebolt 27 permits plate 25 a slight amount of play, this constructionpermits the housing 20 and distributor shaft a slight amount of axialmovement relative to the engine block. The lower side of pinion 16 isslightly spaced from the adjacent end of housing 19 for permitting thismovement. The construction shown and described holds the parts firmlyyet permits a very slight axial movement of the parts. This arrangementprevents binding and overheating occasioned by unequal expansion anyother cause. The angular arrangement of the distributor 1 shaft permitsthe location of the oil pump at the side of the engine in a positionreadily accessible to a mechanic.
